Advanced GMAT Quant by MGMATFinally I have one of the first copies of the Advanced GMAT Quant book in my hands (after pre-ordering it back in October 2010)! I have spent the evening going through it in quite a bit of detail and here are my thoughts:
I got 49 on my quant but at first, I was not very comfortable with questions but as I got to know the book, it is actually very manageable. (and not so intimidating). I am giving it 5 stars for the effort and content; there are weaknesses, but they may not be relevant to you. The book is deisnged for someone who has already covered the 5
MGMAT Math books and/or is scoring above Q44 (70th percentile). That's actually the qualifications outlined on the second page of the book and I strongly agree - do not attempt this book/questions before you have become comfortable with math basics and are at a good level.
Book Overview
The book consists of 9 chapters:
0. Introduction (they even start numbering chapters at zero)[3g, 0e]
1. Problem Solving Principles [4g, 5e]
2. Problem Solving Strategies & Tactics [12g, 14e]
3. Data Sufficiency Principles - this is a very helpful section as DS resources are few and in between [6, 9e]
4. Data Sufficiency Strategy & Tactics [16g, 15e]
5. Pattern Questions (these are progressions/etc)[8g, 15e]
6. Common Terms & Quadratic Templates [5g, 28e]
7. Visul Solutions (Geometry, Statistics, Tables, Charts, etc) [14g, 10e]
8. Hybrid Problems [4g, 10e]
9. Workout Sets (150 GMAT-style questions)
[3g, 0e] stands for 3 GMAT-like questions and 0 exercises
Total GMAT-style questions: 150 in the sets + 72 in the examples
Total exercises: 106
Pros
- Very innovative approach to DS questions (emphasizes consistent approach and involves rephrasing)
- Designed as a class, teaching you through different questions
- Many new (advanced and innovative) strategies for PS and DS
- I like that the PS and DS sections are addressed separately as it is important to distinguish them even though they may cover the same material
- Step by step review of questions in the book as you move along
- Super-detailed explanations
- Comes with online Question bank (no access to CAT's though)
- 150 GMAT-like questions in the back (uncommon for
MGMAT since they most often utilize the questions in the OG)
Cons
- Many question types are mixed together (I found it a bit distracting since I am a single-tasker but it may work for you)
- Guessing strategies (this never works for me). I appreciate another, more advanced approach, but I never seem to be able to use them. I just choose to guess and move on
- Some chapters such as #6 are very short (could we have split others perhaps?)
- Some questions are perhaps too hard? (such as the first three that are clearly there to give you a "reality check")
- No listing of additional OG questions to practice with (would be good to revisit them even if they were covered in the other 5 guides)
- In the chapters, the fractions are written in short hand (1/3) - kind of surprising
- No cheat sheets for things to be memorize (I believe one should know squares, primes, etc)
I guess if you are wondering whether it will face the fate of [[ASIN:1419553429 Kaplan GMAT 800]], I would say not quite. Unlike that book, here you will find a number of strategies structured very well in a flow of a book rather than a collection of hard questions.
My Suggestions
- Read explanations to every question. Even if you got a question right, it does not mean, yo solved it correctly (that is you used the correct approach or found all the shortcusts). You will be surpised sometimes and will pick helpful tips even from explanations of questions you got right
- Follow the actual strategies (DUH). You bougth the book because of them. Yes, there are questions, but the value is in the strategies. Don't just take the fish - go for the fishing pole
- IF you are not comfortable with something and the book does not cover it, don't just glance over it and move on - research and investigate. Get the book or someone to explain to you the missing components
- Memorize the common math elements such as primes, squares up till 20. E.g. what is 15*15? or square root of 3 is approximately how much? 2 to the power of 5 is?
This is it so far. I will edit the review as I continue to discover new elements in this book.
Good luck on your GMAT!
